1. Product overview

KQET-5016 small flow rate 2.83L online laser dust particle counter is a test instrument applied to cleanliness monitoring and micro-particle counting detection in clean environment. The counter is theoretically based on the light scattering principle and realizes the detection of dust particle size distribution and the counting of particle number through photoelectric sensing technology. The instrument has been widely used in clean room testing, filter material testing, mask testing and other industries. This instrument has the characteristics of good stability, high measurement accuracy, small size, light weight, easy installation, etc.
